Hi Kris,
How are you
Recently one of our requirements came up for converging IOR gateway, this
is the gateway which according to bpmn specification syncs up on all
upstream tokens and propagates token when no upstream token is left
Currently jbpm does not support this construct, I was wondering if jbom has
this in roadmap and if you can give some advice on difficulty and state of
implementation

Hi guys.. that's the AND Converging gateway right?
The AND waits for all the branches that are converging before propagate.
If that's not what you are looking for it should be very easy to implement..
and probably you can model that with the complex converge gateway.
Cheers.

So do you want to implement and OR or and AND converging gateway, by the

differences with the AND converging gateway that is currently implemented in
jBPM5?

New subject: Re- IOR gateway
Hi Mauricio,
If an an AND converging gateway has n incoming branches, it expects that all incoming have
been triggered and when it is so - it calls triggerCompleted (so that the rest of the
process can continue)
In case of OR converging, lets assume a process
branch1
/ \
OR (diverging) - branch 2 - OR (converging)
\ /
branch 3
now any of branches may be triggered, OR converging has to wait for all branches that were
actually triggered (say branch1 and branch 3). But the problem is it does not know which
branches were triggered (for AND it was easier - just wait for all branches to be
triggered). here in case of OR - we don't know to continue to wait for branch 2 or
not

Hi Anurag,
Based on your description I think that I'm understanding what do you want to
do now.
Right now the behaviors implemented in jBPM5 are XOR and AND.
I think what you want to implement is N of M converging gateway, as it was
in Drools Flow? Am I right?
You want to wait 2 of the 3 branches that you have to propagate the
execution?

New subject: Re- IOR gateway
Hi there,
just some general remarks from my side:
the semantics and implementation of the inclusive OR-join are far from
trivial. See e.g. references below.
<http://domino.research.ibm.com/library/cyberdig.nsf/papers/331BE249A11C1B3F
852577DE003B5477/$File/rz3791.pdf>
http://domino.research.ibm.com/library/cyberdig.nsf/papers/331BE249A11C1B3F8
52577DE003B5477/$File/rz3791.pdf
<http://www.springerlink.com/content/97413825k6141332/>
http://www.springerlink.com/content/97413825k6141332/
However, I'd be interested in the concrete business requirement you have for
modeling, since from my experience you can cover a very large part of
regular requirements just using the "simple" gateways.

That's what I mention. it can be easy to implement most of the times but
there are also some complex business use case that can complicate the
generic approaches.
Looking at a concrete use case will help a lot to understand what do you
want to achieve.

New subject: Re- IOR gateway
The BPMN spec contains the business requirements and the description of the
functionality of this construct.
Anurag also explained the functionality in this thread.
The questions we have for the jBPM team are:
-is this construct on the roadmap ? if yes, for which release ?
-if yes, is there a way to track its development ?
-Overall, what would the work consist and how hard is it to implement ?
Please advise.

New subject: Re- IOR gateway
Can you please point me in the spec (Pages) so I can review it and give you
some feedback and estimations?
I'm pretty sure that we can use a complex converging gateway to cover that
features, but I would like to be sure that we are talking about the same
thing.
Cheers

The BPMN spec contains the business requirements and the description
of the
functionality of this construct.
Anurag also explained the functionality in this thread.
The questions we have for the jBPM team are:
-is this construct on the roadmap ? if yes, for which release ?
-if yes, is there a way to track its development ?
-Overall, what would the work consist and how hard is it to implement ?
Please advise.

New subject: Re- IOR gateway
Reading the specification, specially the *Inclusive Merge section *
*"The Inclusive Gateway synchronizes a certain subset of branches out of the
set of concurrent incoming branches (merging behavior). "
*
I reach some conclusions that are based on how jBPM5 is doing the handling
of joins and forks:
1) For simple situations we can use the N to M approach. We can specify how
many of the incoming sequence flow will trigger the propagation to the next
node
2) For more complex scenarios where specifying the number of "tokens" that
arrives is not enough we can use a complex converging gateway to define the
logic that needs to be used to propagate the execution to the next node.
I think that I can create an example using a both.. but I want to be sure
that my conclusions fulfill your needs.
Cheers

New subject: Re- IOR gateway
Hi Mauricio,
In case of OR we don't not know at design time how many incoming connections would be
triggered before we propagate token. in example below - it can be only one or two or all
three branches based on runtime data (we can not know the value of N)
So it is more of global search as mardo's links illustrate

However, I’d be interested in the concrete business requirement you have for modeling,
since from my experience you can cover a very large part of regular requirements just
using the “simple” gateways.

Hi Anurag,
Based on your description I think that I'm understanding what do you want to do now.
Right now the behaviors implemented in jBPM5 are XOR and AND.
I think what you want to implement is N of M converging gateway, as it was in Drools
Flow? Am I right?
You want to wait 2 of the 3 branches that you have to propagate the execution?

Hi Mauricio,
If an an AND converging gateway has n incoming branches, it expects that all incoming

In case of OR converging, lets assume a process
branch1
/ \
OR (diverging) - branch 2 - OR (converging)
\ /
branch 3
now any of branches may be triggered, OR converging has to wait for all branches that
were actually triggered (say branch1 and branch 3). But the problem is it does not know
which branches were triggered (for AND it was easier - just wait for all branches to be
triggered). here in case of OR - we don't know to continue to wait for branch 2 or
not

If that's not what you are looking for it should be very easy to implement.. and

But the rule option looks like solve that problem right? If we create a rule or a set of
rules that analyze the context and based on that decide if it should propagate or not,
solve the problem.
I'm not sure if you are dropping the rule idea for some reason.

New subject: Re- IOR gateway
Antoine,
While we would like to support all constructs as defined in the BPMN2
specification, we currently do not support the OR gateway yet. Since it
is a rather advanced construct (especially if you start using it in
combination with (unstructured) cycles), we in general recommend users
to try and avoid this complexity by trying to remodel the business
problem using a combination of (the much simpler) XOR and AND gateways.
Therefore, the construct is not yet on any specific release.
The best way if you want to track progress would be to create a JIRA
issue I would say, that we will then use to report progress when
implementing this feature. It would also allow other users to vote for
this issue to keep track of interest.
The implementation would be an extension of the generic Join node (and
JoinInstance), where the logic to decide when to continue would not only
keep track of the "tokens" that already arrived (as is already done in
the current implementation) but would also check for incoming branches
that don't have a "token" yet whether there aren't any active node
instances that could still reach this incoming branch. In most cases
this can be done by simply traversing the process graph. But we could
add support for complex cases, where the graph reachability analysis is
done during process compilation (to avoid runtime overhead) and to
support more complex cases (where for example the join instance would
need to register as a listener to the process instance to make sure it
is re-evaluated whenever necessary).

The questions we have for the jBPM team are:
-is this construct on the roadmap ? if yes, for which release ?
-if yes, is there a way to track its development ?
-Overall, what would the work consist and how hard is it to implement ?
Please advise.

However, I’d be interested in the concrete business

you can cover a very large part of regular requirements just
using the “simple” gateways.

Hi Anurag,
Based on your description I think that I'm understanding what
do you want to do now.
Right now the behaviors implemented in jBPM5 are XOR and AND.
I think what you want to implement is N of M converging
gateway, as it was in Drools Flow? Am I right?
You want to wait 2 of the 3 branches that you have to
propagate the execution?
Cheers

In case of OR converging, lets assume a process
branch1

OR (diverging) - branch 2 - OR (converging)
\ /
branch 3
now any of branches may be triggered, OR converging has to
wait for all branches that were actually triggered (say

The AND waits for all the branches that are converging before

If that's not what you are looking for it should be very easy

complex converge gateway.

New subject: Re- IOR gateway
I was thinking for a different situation, instead of transversing the
process graph, insert all the nodes in the working memory, allowing us to
create rules to evaluates situations. I was thinking to do something similar
to the declarative agendas, where the activations are inserted. I think that
this feature will be extremely helpful and we can tackle down situations
like this one.
I will probably create a different thread for that.

New subject: Re- IOR gateway
That might be possible, but not sure rules would be ideal to do graph
analysis. While in simple cases this would work, performance might blow
up in more complex cases where more complex reachability analysis is
necessary, which can probably be done upfront during compilation as
well, using specialized algorithms.

something similar to the declarative agendas, where the activations

we can tackle down situations like this one.
I will probably create a different thread for that.

Antoine,
While we would like to support all constructs as defined in the BPMN2
specification, we currently do not support the OR gateway yet.
Since it
is a rather advanced construct (especially if you start using it in
combination with (unstructured) cycles), we in general recommend users
to try and avoid this complexity by trying to remodel the business
problem using a combination of (the much simpler) XOR and AND
gateways.
Therefore, the construct is not yet on any specific release.
The best way if you want to track progress would be to create a JIRA
issue I would say, that we will then use to report progress when
implementing this feature. It would also allow other users to
vote for
this issue to keep track of interest.
The implementation would be an extension of the generic Join node (and
JoinInstance), where the logic to decide when to continue would
not only
keep track of the "tokens" that already arrived (as is already done in
the current implementation) but would also check for incoming branches
that don't have a "token" yet whether there aren't any active node
instances that could still reach this incoming branch. In most cases
this can be done by simply traversing the process graph. But we could
add support for complex cases, where the graph reachability
analysis is
done during process compilation (to avoid runtime overhead) and to
support more complex cases (where for example the join instance would
need to register as a listener to the process instance to make sure it
is re-evaluated whenever necessary).

New subject: Re- IOR gateway
It will be a more declarative approach than running a complicated
algorithm.. I mean for business situations.. not for pure graph analysis.
you are right. That's why the use case that you are trying to tackle down is
extremely important.

New subject: Re- IOR gateway
Kris, how hard would it be to implement this ?

Antoine,
While we would like to support all constructs as defined in the BPMN2
specification, we currently do not support the OR gateway yet. Since it is
a rather advanced construct (especially if you start using it in combination
with (unstructured) cycles), we in general recommend users to try and avoid
this complexity by trying to remodel the business problem using a
combination of (the much simpler) XOR and AND gateways. Therefore, the
construct is not yet on any specific release.
The best way if you want to track progress would be to create a JIRA issue
I would say, that we will then use to report progress when implementing this
feature. It would also allow other users to vote for this issue to keep
track of interest.
The implementation would be an extension of the generic Join node (and
JoinInstance), where the logic to decide when to continue would not only
keep track of the "tokens" that already arrived (as is already done in the
current implementation) but would also check for incoming branches that
don't have a "token" yet whether there aren't any active node instances
that
could still reach this incoming branch. In most cases this can be done by
simply traversing the process graph. But we could add support for complex
cases, where the graph reachability analysis is done during process
compilation (to avoid runtime overhead) and to support more complex cases
(where for example the join instance would need to register as a listener to
the process instance to make sure it is re-evaluated whenever necessary).

New subject: Re- IOR gateway
Antoine,
I don't think it would be too difficult to implement, most of the logic
/ state is already there (collecting and storing the "tokens" etc.), it
just needs a new type of Join that follows the logic as defined in the
BPMN2 spec. A first step could just put the logic to determine whether
to continue or not by traversing the graph in the JoinInstance. For
more complex cases, an approach where the graph is traversed for each
Join node during process compilation could be done if this is necessary
for performance reasons.

The questions we have for the jBPM team are:
-is this construct on the roadmap ? if yes, for which release ?
-if yes, is there a way to track its development ?
-Overall, what would the work consist and how hard is it to
implement ?
Please advise.

However, I’d be interested in the concrete business
requirement you have for modeling, since from my experience
you can cover a very large part of regular requirements
just
using the “simple” gateways.

Hi Anurag,
Based on your description I think that I'm
understanding what
do you want to do now.
Right now the behaviors implemented in jBPM5 are XOR
and AND.
I think what you want to implement is N of M converging
gateway, as it was in Drools Flow? Am I right?
You want to wait 2 of the 3 branches that you have to
propagate the execution?
Cheers

Hi Mauricio,
If an an AND converging gateway has n incoming branches, it

In case of OR converging, lets assume a process
branch1
/ \
OR (diverging) - branch 2 - OR (converging)
\ /
branch 3
now any of branches may be triggered, OR converging has to
wait for all branches that were actually triggered (say
branch1 and branch 3). But the problem is it does not know
which branches were triggered (for AND it was easier - just
wait for all branches to be triggered). here in case of
OR -
we don't know to continue to wait for branch 2 or not

If that's not what you are looking for it should be
